NCEES Practice Exam 2011 Transpo question 116

I get a factor of safety of 3.05 and disagree with the solution of 2.8. Am I missing something? The difference is in the moment arm of the triangular section of concrete. I say the distance is 2/3x2', the solution says 2/3'.

Do you know if the 2004 Green book has an errata... I looked on the website but didn't find anything.

I wondered the same thing when I started my studies. Like you, I didn't see anything on-line so I e-mailed AASHTO and asked. They told me they do not have any errata for the 2004 GDHS. However, I believe there is errata for the 2006 Roadside Design Guide.

Also, question 116 is the same for all 5 NCEES civil sample question books.

I agree, but the problem with the PPI books is the web site for the Errata submissions is down almost every time I try to submit. Frustruating.

Jason, what's weird is I have problems with the PPI errata link at home but not at work so it could be a 'per computer' problem. If you want to list your PPI books (title, printing, edition), I can look up the errata for you and e-mail it to you.
